Image capturing module and electronic device

Abstract

An image capturing module includes an imaging lens system, an image sensor, a first circuit board, at least three passive components, and a second circuit board. The image sensor is at an image side of the imaging lens system and having a photosensitive area corresponding to the imaging lens system. The image sensor and the passive components are disposed on the first circuit board. Each passive component has a first lead and a second lead. The second circuit board corresponds to the first circuit board and includes a connector and multiple circuits electrically connected to the connector. The first leads and the image sensor are electrically connected and disposed on the first circuit board. The second leads form a contact on the first circuit board. The number of the contact is less than the number of the passive components. The contact is electrically connected to at least one circuit.
